It is time for Pakistan to amp up the pressure on the crazy mullah regime ruling Iran. Time to neutralize their pets inside Pakistan and time to show them where they belong in the grand scheme of things.
If Pakistan forgets this episode and the role the Iranian regime played in it, then that would be a great loss for the Pakistani state. Time to take the KSA into full confidence about the security of the region. The sooner the crazy regime in Iran is replaced with a normal one, the better it is for everyone in the region and beyond. The presence of the the current regime in Iran also means there won't be much peace in Afghanistan because the Iranians see everything purely from an extreme sectarian lenses. The Arabs at the least are about business and can be handled easily.
